KNX Binary Sensor


The knx sensor platform allows you to monitor KNX binary sensors.

The knx component must be configured correctly, see KNX Component.

# Example configuration.yaml entry
binary_sensor:
  - platform: knx
    name: "Entrance.Motion.Sensor"
    address: '6/0/2'
    device_class: 'motion'
    #significant_bit: 2

Configuration variables:

  • name (Optional): A name for this device used within Home Assistant.
  • address: KNX group address of the binary sensor.
  • device_class (Optional): HASS device class e.g. “motion”.
  • significant_bit (Optional): Specify which significant bit of the KNX value should be used. Default is 1.

You can also attach actions to binary sensors (e.g., to switch on a light when a switch was pressed). In this example, one light is switched on when the button was pressed once and two others when the button was pressed a second time.

# Example configuration.yaml entry
binary_sensor:
  - platform: knx
    name: Livingroom.3Switch3
    address: '5/0/26'
    automation:
      - counter: 1
        hook: 'on'
        action:
          - entity_id: light.hue_color_lamp_1
            service: homeassistant.turn_on
      - counter: 2
        hook: 'on'
        action:
          - entity_id: light.hue_bloom_1
            service: homeassistant.turn_on
          - entity_id: light.hue_bloom_2
            service: homeassistant.turn_on

Configuration variables:

  • name (Optional): A name for this device used within Home Assistant.
  • counter (Optional): Set to 2 if your only want the action to be executed if the button was pressed twice. To 3 for three times button pressed. Defaults to 1.
  • hook (Optional): Indicates if the automation should be executed on what state of the binary sensor. Values: “on” or “off”. Defaults to “on”.
  • action: Specify a list of actions analog to the automation rules.
